To all whom it may concern: v I

Be it known that L-Tnnooonn R. TR'EI- BER, a-citizen ofthe United States, residing at Kansas City, in'the county-.of Jackson and State of Missouri, have invented certain new and useful Improvements-in Powder-Disseminators, of which the following is a specification. 2 My invention relates to improvements in an object of my invention n1. provide a powder disseminator with which powder may be-evenly disseminated iii-small charges and'over' a relatively-small surface;

The novel features ofmy-invention are hereinafter fully described and claimed In the accompanying drawings illustrative of therpreferred form of. my invention, Figure 1 is aside elevation. -Fig. 2 is a sectional 'view on the dotted line 0-6 of Fig. 1. Fig. 3 is a top view. 'Fig. 4 is a cross section on the dotted line c-d of Fig. 2.

Similar characters similar parts.

1 denotes a-powder receptacle in the form with a erforated screw cover 2 on which is mounte a resilient cap 3 of any desired shape, but preferably provided with a central nipple 4 havin a discharge opening,

slit 5; is preferably, but not necessarily,

normally closed by the resiliency of thematerial forming the cap.

Preferably, as shown inFig. 3, the nipple'4 has a. flat top' or outer'wall-and side ls. With this construction the slit will not split and enlogrge withv use, and the end wall effect :an opening-of the-.slit,-upo n squeezing of the cap, moreefiectively than I nipple.

' the-ca with a structure in which the side walls are amount of powder to pass through-the per-- forations 6 of the cover-2 into the cap 3.: .If

he -dischai'ged therethrough in a small evenly distributedwcharge: ()wing' to-.;the cover permitting but a small amount of ,powder to. enter the cap- 3 at a' time, no

, tightlycom plbeithe'n squeezed so as to expand "or 'open t e slit 5, the powder in the cap will care is required to prevent too much being discharged from the cap. If the perforated cover were not present a large amount of powder-would pass into the cap as soon as the bottle is inverted, and unless great care were used more powder would be discharged upon squeezing the cap than would be. desirable. If the cap were-omitted from-the structure, the device would disseminate the powder over too great a surface suitable for some purposes.

Preferably the screw cover-2 is provided w1th' a screw threaded outer periphery on which is detachably fitted the, resilient cap 3, asshown in Fig.2. By mounting, the cap on the detachable cover 2 the cap and cover may both be detached in one operation. By

having the cap embrace the outer periphery.

of. thecover. and the ca being resilient, a firmhand holdis provi ed for the turning of the cover which may sometimes'be diflicult. By having the outer periphery of the cover screw threaded, as shown, the cap 3 may be securely held and yet may be easily detached from the cover.

.- It will be noted that the outer screw cover to enable both to be turned for simultaneous removal from the bottle. Furthermore. the rounded threads will-not cut the softmaterial offthe cap when the cap ;is

pressed against the threads. By employingt e resilient cap on the periphery.

of.the cover acompressible'hand hold is provided by which, on compression, the' cover may be'firmly gripped so as tobe turned for the simultaneous removalof the cap and cover-from -the bottle. This is a function which is not effected in either of the devices of Pomeroy or Mitchell. Inasmuch as the combination of the two old elements effects anew function noteflected in either of the old combinations, the newcombination is 'patentable." i I i Ijdo'not'confine my invention to the pres cise structure illustrated anddescribed, as 'variousmodifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

Having thusdes'cribed my invention, what I claim and desireto secure byLetters Patent,- is

' 1. -In a powder disseminator, the combination with a receptaclefor powder having peripheral screw threads, of a perforated cover fitted to the threaded periphery of the receptacle, and having rounded screw threads on its outer periphery, and a perforated resilient cap mounted on and engaging the threaded outer periphery of the cover.

2. In a powdendisseminator, aresilient cap having a nipple provided with side Walls and an outer end wall, the end wall having a slit theret-hrough which does not extend through the side walls, the side Walls of the nipple being thicker than the end wall thereof.

' In testimony whereof I have signed my 15 name to this specification in presence of two subscribing witnesses.
